Is it a letter, or is it an internal dialog, a letter that will never be written? One suspects the latter, since so much is unsaid between the two lovers. Your language is expressive and reveals a complex history between two people who, though very much in love, will never be together.
What is the barrier to a life together? The writer suggests that it is the lovers themselves who will follow a cycle of rebuilding and destroying. Why? Because love, and people are irrational perhaps.
There is one point in the story that the reader wonders is perhaps an error: at the end of paragraph 5
Then the long awaited 27…
Did you not mean 26? Is that not the number on which the lover would arrive? 27 takes you away, does it not?
In any event, a very good story. Thank you for sharing it with us.
